| 英文摘要 | effective hydrolysis of chitosan, the n-deacetylated product of chitin, remains challenging. here, we report acid-promoted hydrolysis of chitosan in imidazolium based ionic liquids with good total reducing sugars (trs) yield under mild conditions. trs yield reached over 60% in the presence of about 6.0 wt% concentrated hydrochloric acid at 100 degrees c within 7 h. kinetic modeling of a typical experimental data set suggested that the hydrolysis most likely followed a consecutive first-order reaction sequence, where k(1) and k(2), the rate constants for trs formation and degradation, were determined to be 0.01372 and 0.00015 min(-1), respectively. our method may be useful to explore new applications of natural chitin resources.
